VALPES Electric Actuator with POSI Positioner

The POSI positioner module is integrated with VALPES electric actuators for proportional valve positioning in process control. It accepts analog control signals 0–10 V or 4–20 mA and enables intermediate valve positions, not just open/close operation. Suitable for actuators rated from 20 to 2400 Nm torque.

Compatible Series

  • ER PLUS
  • VR / VS
  • VRX / VSX ATEX
  • LT low temperature
  • DV / DVX DNV-GL & ATEX
  • VT PLUS
  • MT multiturn

Control Operation

The positioner compares the analog setpoint with the feedback signal and adjusts actuator angle or stroke accordingly. Feedback options include 4–20 mA or 0–10 V. Features include reverse action, training mode, Bluetooth via AXMART (P8 option), and Modbus-RTU in the same configuration.

Technical Specifications

  • Duty cycle: S4 50% per IEC34
  • Operating temperature: -20 to +70 °C
  • Integrated anti-condensation heater
  • Electronic torque limiter
  • Manual override via handwheel or output shaft
  • 4 adjustable limit switches, 5 A
  • Multivoltage power supply
  • Enclosure: IP66 to IP68 10 m / 72 h (series dependent)

Process Applications

Used for dosing, flow control, filling, mixing, and applications requiring the valve to remain at intermediate positions. Media compatibility depends on valve selection: water, air, seawater, auxiliary gases, fuels, or chemical networks.

FAQ

When is POSI selected over on-off?
When the PLC or BMS requires analog valve positioning, not just open/closed states.

What is checked during maintenance?
Control signal, feedback, limit switches, cable glands, enclosure sealing (IP), torque limiter, and actuator-to-valve torque matching.
